Carrot or Stick!

As a self-help expert it
is important for me to understand what inspires my clients either in a group
training session or in a one-to-one session. I describe motivation as the
reason that a person is willing to do something. I believe that in general
there are two main reasons why people do something ‘Carrot or Stick’. A person
motivated by a carrot is thinking about the good thing that they will get if
they for example, achieve a goal. A person motivated by a stick is thinking
about the not so good that will happen if they for example, do not achieve a
goal.
I have two questions for you:

Ø Is David Goggins driven by a carrot or stick,
(if you don’t know who this person is you must check him out)?
